Application filed April 26, 1916.

To all whom it may concern:

Be it known that I, THOMAS A. Common, a citizen of the United States ofAmerica, residing at the city of Mount Vernon, county of Jefferson, inthe State of Illinois, have invented a certain new and useful Carlineand Process of Making the Same, of which the following is such a full,clear, and exact description as will enable any one skilled in the artto which it appertains to make and use the same, reference being had tothe accompanying drawings, forming part of this specification.

My invention relates to a carline and the process for making the same,and more particularly to a carline formed of a single piece of sheetmetal, and to the process of forming such a carline with the leastpossihis number of operations.

In the accompanying drawings, which illustrate one form of carline madein accordance with my invention, Figure 1 is a view showing the blank ofwhich the carline is to be formed; Fig. 2 shows the same blank after thefirst operation of bending has been performed thereon; Fig. 3 shows thecompleted carline; Fig. 4: is an enlarged sectional view of on'ehalf ofthe carline, together with some of the parts of a railway car to whichthe carline is to be applied; and Fig. 5 is an enlarged perspective viewof one end of the carline.

Like marks of reference refer to similar parts in the several views ofthe drawings.

The first operation in forming my carline is to stamp out a blank likethat shown in Fig. 1. The blank may be made of a sheet of steel or othersuitable metal. This blank has a slot 10 formed therein, dividing thecenter of the blank into an upper part 11 and a lower part 12, which arepreferably of the same width. The ends of the blank may be somewhatreduced in width as shown in the drawings, but this is not essential.Each end is provided with a pair of slots 13 and 14, dividing the endsinto a long upper eX- tension 15, a short lower extension 16, and acentral extension 17.

After the blank has thus been formed, by means of a suitable die, aportion of the upper edge is turned over to form a flange 18, and aportion of the lower edge is turned over to form a flange 19, preferablyeXtending in. opposite direction from the flange 18 so as to form aZ-bar, as best shown in Fig. 5

of the drawing. At the same time that these flanges 18 and 19 are turnedover the central projections 17 of the ends are turned over at rightangles to the body of the carline to form fastening means for securingthe carline in position.

After this operation has been performed the blank is heated and by meansof suitable dies, while the blank is hot, the ends 15 and 16 are bentdown, as best shown in Fig. 5 of the drawings, so as to form fasteningmeans for the carline, and at the same time the two parts 11 and 12 ofthe carline are separated, the upper part 11 being elongated and bent toform a truss-member, while the lower part 12 is maintained as nearly aspossible straight so as to form a tie-member. This operation completesthe carline, except for fastening in position a strut 20, extendingbetween the members 11 and 12 at the center of the carline. The turnedover ends 15 and 17 are provided with holes 21 for the passage of a bolt22 which secures the same to the side plate 23 of a car. The overturnedend 16 is also provided with an opening 24 adapted to receive a bolt 25,the same passing through the side plate 23 of the car. The carline maybe also provided with suitable bolt holes 26 for securing the purlins 27in position, and also for securing the fillerblock 28 in position when afiller-block is used.

By forming my carline of a single piece of sheet metal I am enabled notonly to form the article with the minimum number of operations, but alsoto increase the strength of the carline. It will be obvious that whenknee-irons are riveted to the body of the carline, the entire carlinecan be no stronger than the rivets securing the pieces together. Anotherobject which I obtain by forming my carline of a single piece is that byso forming the carline the distance between the ends of the carline canbe made more uniform than where the carline is built up of a number ofseparate pieces.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent of the United States is:

1. The process of making a carline which comprises forming alongitudinal slit in a flat blank of metal, bending the edges of saidblank to the right and left to produce oppositely projecting flanges,heating the blank, separating the parts of the blank to form truss andtie members, and bending the ends of the blank to form knee-irons.

2. The process of making a carline which comprises forming alongitudinal central slit and two pairs of end slits in a fiat blank ofmetal, bending the edges of said blanl; to the right and left to formoppositely projecting flanges, heating the blank, separatingthe parts ofthe blank to form truss and tie members, bending the horizontal portionsof the ends downwardly to form fastening means, and bending theperpendicular portion of the ends laterally under the upper horizontalportion to form additional fastening means,

3. A carline of Z-cross section having an extension of its upperhorizontal flange adapted to extend across the side plate 01' a car, adownward projection carried by said extension, a turned over portion ofthe vertical flange extending under the upper horizontal flange andadapted to bear on the side plate of the car opposite said downwardprojection and forming fastening means for securing the carline inposition and a downward projection of the lower horizontal flangeadapted to form additional means for securing the carline in position.

In testimony whereof, I have hereunto set my hand and afiixed my seal.
